Alabama center Barrett Jones tried to remain calm in front of the television Saturday night when Baylor took an early lead on Kansas State, No. 1 in the B.C.S., and Stanford stood toe-to-toe with No. 2 Oregon. But when the Bears put away the Wildcats and the two-loss Cardinal shocked the Ducks, Jones said he and his friends became rather “uncomposed.” They left his apartment near The Strip on campus and joined the many revelers in the street.

And with that, a nervous week for the Southeastern Conference had come to an end. Alabama (10-1), little more than a week removed from a home loss to Texas A&M, is in control of its fate again, as is Georgia (10-1), giving the SEC two teams with a solid chance to play for the Bowl Championship Series title and run the league’s streak of national championships to seven.

“We haven’t won the West yet — we still have to beat Auburn — but it’s a good feeling not to have to depend on others,” Jones said of winning a division title. “It was pretty wild around here Saturday night; people were running all over the streets.”

Alabama moved to No. 2 in the B.C.S. standings and was poised to beat Auburn (3-8) in the Iron Bowl rivalry game Saturday and set up a matchup with No. 3 Georgia in the SEC championship game on Dec. 1. The winner of that game, presumably, will play for the national title.

And so the polarization of college football — the SEC versus everyone else — continues. Jimbo Fisher, the coach of Florida State, which has one loss and plays in the Atlantic Coast Conference, has already complained about the Seminoles’ being ranked behind teams from the SEC with one loss.

Indeed, the commentators for Saturday night’s national broadcasts of Kansas State-Baylor and Stanford-Oregon ignored the possibility that one-loss Florida State, one-loss Oregon or one-loss Kansas State could potentially face an unbeaten Notre Dame for the national title. They leapt right to the conclusion that Alabama would climb to No. 2, Georgia would be No. 3, Florida would be No. 4 and the winner of the SEC championship game would get a date with the Irish.

The SEC’s résumé in recent years is unmatched, but the league’s teams have not merely been good during this run of titles. They also have been lucky. In 2006, Southern California was upset late in the season and Florida squeezed into the national championship game. In 2007, two-loss Louisiana State got in the title game when Pittsburgh upset West Virginia. This season, unbeaten Ohio State would be ranked ahead of the one-loss SEC teams, but the Buckeyes are ineligible for the postseason because of N.C.A.A. violations.

Alabama is not the only team giddy about upsets. Georgia still has to beat Georgia Tech on Saturday and play in the SEC championship game, but the Bulldogs could not restrain their glee on Twitter. “Thank you Baylor thank you Stanford,” cornerback Sanders Commings wrote Saturday night.

On Sunday morning, he added: “And I wake up pinching myself. Yea it’s real. We control our own destiny.”

Twenty years ago, SEC coaches bemoaned the creation of the conference’s championship game, insisting teams were already handicapped by a difficult regular-season schedule. Now the SEC has a chance to win its seventh straight championship and the caliber of the conference — five teams in the top 10 in the Associated Press poll — is more of a help than a hindrance. For another week, at least, the dominance of the SEC continued.
